Andrew got copyrights updated and wants to get that Snow machine configuration in. Intends to come back to sparse variables now.
Joshua Brown has performance metrics app working. https://github.com/lanl/parthenon/wiki/JoshuaSBrown-app_for_parthenon_develop
Carola nothing to report this week.
Jonas got Kokkos random number generation for RIOT proxy working. All time is spent in packing fields now - needs to merge in develop. Can't get on RZAnsel because of inaccessibility of ihpc-gate. Will use Darwin P9 until he gets approval. https://github.com/lanl/parthenon/pull/406
Joshua Dolence thinks we need some new work on Boundary conditions. He'll try to work on it in his own time or hope that somebody else might jump into it. Next week he might look into it. Joshua will schedule a meeting for next week on this.
Jonah Miller did some minor stuff on the Parthenon side. Added a fix to package registration to avoid duplication of the package label. Did some work to get RIOT up to date with new pack-in-one.
Ben - implemented MPI for particles. Used existing boundary structure.
Phil finished pack-in-one and got it merged. Filed a bunch of issues to look into AMR performance. Would like a more realistic proxy app.
Phil wants to know what number of levels we want to target. Andrew thinks it's 6-7 levels. Josh really wants to map out the parameter space in terms of trade offs between refinement and performance. Jonah would like to explore the effects of different coordinate systems.
Functionality is currently broken. Somebody needs to build this back up. https://github.com/lanl/parthenon/issues/429
We should run Jonas' proxy and the AthenaPK. Jonas will run on Darwin Power9 to validate it's running and ~scaling. Phil wants to run AthenaPK, as well. Will design a test case matching our hypothetical proxy application.
15 minute sync up on Monday or Tuesday. Required: Andrew, Galen, Phil, Jonas. Optional, but likely interested: Jonah
Targeting next Friday.
